Let's divide 643804 by 83
The aim is to understand the frequency of 83 in 643804.

Moving on to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 83

Let's proceed to step 2:
83 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 83

Let's proceed to step 3:
83 goes into 643 7 times with a remainder of 62.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 581 from 643 to get 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 83

Let's proceed to step 4:
When dividing 628 by 83, we get 7 with a remainder of 47.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 581 from 628 leaves us with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 83

On to step 5:
83 can be fit into 470 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 775.0
Subtracting 415 from 470 leaves us with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 83

Let's proceed to step 6:
83 can be fit into 554 6 times, resulting in a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 7756.0
Subtract 498 from 554 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
560 divided by 83 is 6 with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 7756.6
Subtract 498 from 560 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
When dividing 620 by 83, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7756.67
If we take 581 away from 620, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
83 goes into 390 4 times with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 7756.674
Subtract 332 from 390 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
83 can be fit into 580 6 times, resulting in a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 7756.6746
Subtract 498 from 580 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 11:
When dividing 820 by 83, we get 9 with a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 7756.67469
If we take 747 away from 820, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 12:
730 divided by 83 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 7756.674698
Subtracting 664 from 730 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
83 goes into 660 7 times with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 7756.6746987
If we take 581 away from 660, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 14:
790 divided by 83 is 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 7756.67469879
Subtracting 747 from 790 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 7756.67469879 with a remainder of 4.3e-08.
